pdftex can operare in two modes: dvi and pdf. In dvi mode, this is more
or less the same than good-old-tex (even in dvi mode, you can make use
of typographic extensions, to that's one advantage of using the pdftex
engine by default).
Most people think that pdftex can only produce pdf but this is just
wrong. It could produce dvi as well since its fist version. Even more,
the default mode is dvi, so you have to set \pdfoutput to something
non-zero to get into pdf mode (this is done in the .ini files which
generate the formats such as pdflatex, pdftex, pdfetex).
Try this:
cd /tmp
pdftex -ini plain\\dump
pdftex \&./plain story\\end
rm -f plain.fmt
None of the loaded files touches the \pdfoutput variable. And what do
you get? story.dvi!
For LaTeX users, teTeX-3.0 has a latex format name and a pdflatex
format name. Both are using the same latex macros and both are using
the pdfetex engine. The only difference is that latex has \pdfoutput=0
dumped into latex.fmt and pdflatex.fmt has \pdfoutput=1.
So, users just can switch between dvi and pdf mode of the engine by
invoking the right command. There is no need to fiddle around with
manipulating \pdfoutout.
$ latex small2e
...
Output written on small2e.dvi (1 page, 1780 bytes).
$ pdflatex small2e
...
Output written on small2e.pdf (1 page, 32587 bytes).

If you are in dvi mode, you can use dvips with eps graphics as usual.
